Understanding the Basics: Chametz vs. Kitniyot
To grasp why peanuts are a point of debate, it's crucial to understand the distinction between two categories of forbidden foods during Passover: chametz and kitniyot. The Torah explicitly prohibits consuming chametz—any leavened product from wheat, barley, rye, oats, and spelt. The prohibition of kitniyot, however, is a rabbinic decree, a custom known as a minhag, that evolved in the Middle Ages among Ashkenazi Jews in Europe.
The Historical Rationale for the Kitniyot Ban
The prohibition of kitniyot—which includes foods like rice, beans, corn, and peanuts—was developed for several reasons. One concern was that these foods were often stored or harvested near chametz grains, leading to potential confusion or cross-contamination. In pre-industrial times, it was difficult to guarantee that a bag of dried beans or corn would not contain kernels of wheat or barley. Another reason was that kitniyot could be milled into a flour and baked into products that looked like chametz, and the sages worried this would lead people to mistakenly consume actual chametz during Passover. The custom served as an extra layer of precaution, ensuring no one violated the biblical prohibition of eating leavened bread. Since peanuts are botanically legumes and not nuts, they fell under this kitniyot classification for many Ashkenazi communities.
Ashkenazi vs. Sephardic Traditions: A Tale of Two Customs
Jewish communities around the world developed different traditions regarding kitniyot. The ban became widely accepted among Ashkenazi Jews, whose ancestors came from Central and Eastern Europe. In contrast, Sephardic Jews, whose heritage traces back to Spain, North Africa, and the Middle East, never adopted the custom and have traditionally continued to eat kitniyot during Passover. This fundamental difference in custom illustrates the rich diversity of Jewish practice and explains why a Sephardic Jew might enjoy peanut butter during Passover, while an Ashkenazi Jew would not. A modern development has seen the Conservative movement, in 2016, formally sanction the eating of kitniyot during Passover, aligning its practice more with Sephardic traditions.
The Kosher Status of Peanuts Year-Round
It's important to clarify that this prohibition applies specifically to Passover. During the rest of the year, peanuts are perfectly kosher, provided they are processed under reliable kosher supervision, like any other processed food. The kosher certification ensures that the peanuts have not been processed using non-kosher equipment or mixed with non-kosher ingredients. Raw, unflavored peanuts do not inherently require rabbinic supervision, but if they are roasted, flavored, or otherwise modified, they must bear a kosher symbol.
The Modern Debate and Personal Choice
In recent decades, there has been a debate over the relevance of the kitniyot ban in modern times. With advanced processing and labeling, the risk of cross-contamination and confusion between grains and legumes is minimal. As a result, some contemporary rabbinic authorities have re-evaluated the custom. For instance, Rabbi Moses Feinstein, a highly respected 20th-century Orthodox authority, issued a lenient ruling allowing peanuts on Passover, arguing that the original reasons for the ban didn't apply to New World crops. Despite this, many Ashkenazi communities continue to observe the stricter custom out of reverence for long-standing tradition. The decision often depends on an individual's family heritage and the specific rabbinic guidance they follow.
Comparison Table: Kitniyot on Passover
| Feature | Ashkenazi Custom | Sephardic Custom |
|---|---|---|
| Stance on Peanuts | Generally forbidden (as kitniyot) | Generally permitted (as they are not chametz) |
| Stance on Kitniyot | Historically avoided, including rice, corn, and legumes | Traditionally permitted; some communities avoid dried pulses |
| Origin | Custom (minhag) developed in medieval Europe | Does not follow the custom, based solely on biblical law |
| Modern Adaptations | Some movements (e.g., Conservative) have lifted the ban; some individuals follow more lenient Orthodox opinions | No change in practice regarding peanuts or most kitniyot |
The Bottom Line: Personal Tradition and Kashrut
Ultimately, whether or not a person eats peanuts on Passover is a matter of personal and communal tradition. For a Jew of Ashkenazi descent, the avoidance of peanuts is a custom passed down through generations, a way to honor the legacy of their ancestors. For a Sephardic Jew, enjoying peanuts is a normal part of the holiday, as their community never adopted the ban. The existence of different customs highlights the rich tapestry of Jewish observance. It's also a powerful reminder that strict adherence to a particular interpretation of Jewish law is a deeply personal and meaningful choice.

Conclusion
So, why aren't peanuts kosher for some people during Passover? It all comes down to a centuries-old rabbinic custom, not a biblical commandment. The kitniyot ban was created to prevent confusion and cross-contamination with chametz, the forbidden leavened grains. While Ashkenazi Jews have traditionally avoided peanuts due to this custom, Sephardic Jews have not. Modern shifts in Jewish law and improved food processing have led to new discussions, but for many, the tradition remains a significant part of their Passover observance. The answer, therefore, is not a simple yes or no, but rather depends on one's specific Jewish heritage and traditions. Always look for a reliable kosher for Passover certification on packaged products to be certain.
